Completely fair question, and the—hopefully unsurprising—answer is no. To start with, my passion is for Microsoft products and technologies (I work for the company I love!). And for the same reason the quarterback on the other team doesn't throw passes to my
guys, we're heading towards our own end zone. I'm sure the other team has their own plays and strategies. But at the end of the day, it's healthy competition that pushes innovation, and I'm happy to have it.
From a technical perspective, writing a SWF file is different than reading it, and it would take quite a bit more effort. I'm not just talking about the bits and bytes but also the data formats. There was a company called Xamlon that wrote
a XAML to SWF tool, but I just tried to pull up their web site, and they must be in the middle of retooling (http://www.xamlon.com/).
